New Houston Texans coach Bill O’Brien isn’t waiting around to make changes to his staff.

On Saturday, defensive coordinator Wade Phillips, who was the team’s interim coach for the final three games of the season, and offensive coordinator Rick Dennison were fired after meeting with O’Brien.

Thanks to McNair family and great Texan fans and most all our players. It was wonderful being home. I wish the best to all

According to the Houston Chronicle, O'Brien is considering Romeo Crennel as a replacement for Phillips. Crennel was defensive coordinator in Cleveland, New England and Kansas City, as well as head coach with the Browns and Chiefs.

The Texans fired coach Gary Kubiak late in the season and finished with a league-worst 2-14 record. Dennison had been the team's offensive coordinator since the 2010 season; Phillips had been with the team since 2011.

The Texans have the No. 1 pick in the 2014 NFL Draft, but Texans owner Bob McNair told ESPN.com he'd be willing to trade down.

Phillips took his firing gracefully. "Thanks to McNair family and great Texan fans and most all our players," Phillips tweeted. "It was wonderful being home. I wish the best to all.

He directed the team for a game after Kubiak had a mini-stroke Nov. 3 at halftime against the Indianapolis Colts. The Texans lost their last 14 games to finish an NFL-worst 2-14.

Phillips, 66, is the son of late Bum Phillips, who coached the Houston Oilers in their best NFL seasons. He spent three years with the Texans. He was the head coach in Denver, Buffalo and Dallas and served as interim coach with Atlanta and New Orleans.
